On October 20, 2025, U.S. Customs and Border Protection (CBP) issued a bulletin via its Cargo Systems Messaging Service (CSMS) announcing upcoming changes to the Automated Commercial Environment (ACE) Secure Data Portal (ACE Portal). 

According to the notice, will automate the process to apply for a top account in the ACE Portal with an "Importer" sub-account view. For trade parties with a CBP Form 5016 on file, but without ACE Portal account access, the enhancement "will modernize the process for accessing the Importer sub-account features available in the ACE Portal." 

Any applicant utilizing the modernized application tool will receive a verification code to the email address specified on the 5106. CBP "advises all parties with 5106 records on file with CBP to ensure that the contact information listed, including email address and phone number, is current."
